采用自适应超短脉冲激光加工、高数值孔径聚焦和轴向多加工方案相结合的方法，在单晶金刚石表面下嵌入高质量的石墨丝。线创建微米和亚微米尺寸，可以遵循钻石内的任何三维路径。测得的电导率是超过一个数量级大于以前报道的线制造的超短脉冲激光。该方案中石墨化控制水平的提高对于平行于金刚石表面的线的制造显得特别重要。(C)2014 AIP Publishing LLC.
High quality graphitic wires embedded beneath the surface of single crystal diamond are fabricated using a combination of adaptive ultrashort pulsed laser fabrication, high numerical aperture focusing, and an axial multi-fabrication scheme. Wires are created with micrometer and sub-micrometer dimensions that can follow any three dimensional path within the diamond. The measured conductivities are over an order of magnitude greater than previously reported wires fabricated by ultra-short pulsed lasers. The increased level of graphitization control in this scheme appears particularly important for fabrication of wires parallel to the diamond surface. (C) 2014 AIP Publishing LLC.
